As hinted to by Marcin, putting a false surface on a meteorite is anything except natural! It would not be an authentic surface. You could as well electroplate it with gold. Cleaning on the other hand removed the natural surface. IMO if you clean it and get bare metal, it is best to learn to like the surface. If it is too bright, rub it in a little mineral oil under the assumption that it is for 'protection' and removable anytime. That can darken it.

Happy Holidays

Hello, I have a question.As we know an iron meteorite, such like Campo del Cielo for example, have a black surface.I have here a deeply rusted Campo, I'm planning to remove rust with a sand blasting process.But with this I will obtain a greysh surface, like naked iron, the same color of a slice.Not really a natural color for the exterior of an iron meteorite and also not aestetically pretty, looks too artificial for me.There is something to do for restore the original black color?Or it's better to remove the rust with a traditional steel brush, maybe with a drill ???Tips for mechanical or chemical process are welkomme!!!I can try with the classical NaOh bath, I have also Phosphoric, Citric and Oxalic acid :)Thanks<x>x<x>x<x>Francesco---Questa e-mail ? stata controllata per individuare virus con Avast antivirus.https://www.avast.com/antivirus______________________________________________Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com
